What happens to your fuel efficiency when you drive with constant braking and accelerating?

Fuel efficiency drops

Explanation:

Aggressive braking reduces the car’s speed drastically than necessary (even to a halt) hence requiring more gas when accelerating back to the required speed. Gentle braking saves on the forward  momentum of the car when immediately required to accelerate back again to normal speed. This bad driving technique can reduce fuel efficiency by 10 – 40 %.

maybe the spark is gone, love is a weird emotion and there is a possibility he may have found somebody else.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
